partitionBy is a suggestive field. If your value is bigger then what spark calculates(based on the obvious you stated) your value will be used. But repartition is a forced shuffle (but give me exactly required number of partition) operation. You might have noticed that repartition caused a bit of delay(due to shuffling)
